The invention relates to an improved method and to an improved device for degassing polymer melts and for neutralizing the thus produced pollutants, characterised by the following characteristics: said pollutants are guided to a plasma source after removal from the degassing area and prior to adding to a filter step or a separator, said plasma source being built and/or formed such that in said plasma source, the pollutants are transformed, entirely or partially, in a plasma aggregate state.

Plasma exhaust purification

An improved device for degassing polymer melts is characterised by, inter alia, the following features: the at least one vacuum separator comprises cooling pipes extending parallel to each other in the tank interior of the vacuum separator housing, the cooling pipes are double-walled, the cooling pipes end at a distance above a collection chamber or above the tank bottom of the vacuum separator housing, and a cleaning device having a scraper or a wiper is provided, said cleaning device being adapted to the cross-sectional shape of the cooling pipes and preferably to the course of the inner wall of the vacuum separator housing and being movable at least in a partial height at least to the lower end of the cooling pipes.
